Renaming Tests Discussion

**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**

I am starting the discussion on how we want to rename some of the tests post the refactoring of the tests in #1491

**Describe the solution you'd like**

Some of the tests have names that don't necessarily have anything to do with what they are testing. Most universally the tests that begin with `csv_*` come to mind. Does that prefix have any value? I think we should just universally remove them. Maybe another suggestion maybe to instead prefix tests with what functionality they are meant to actually test?

**Describe alternatives you've considered**

Not renaming them?

**Additional context**
Add any other context or screenshots about the feature request here.

Start by reviewing the test refactoring in #1491 and inventorying the tests with the `csv_*` prefix. The issue is a naming discussion rather than a defined edit; done requires an agreed naming convention and updated test names that clearly describe the functionality they cover.
